Robert had a suggestion in the past that helped me track down a similar issue in the past. From an earlier post from him:
One way of pinpointing the error better is to enable fine grained error checking in the osg::State by setting the env OSG_GL_ERROR_CHECKING to ON, on my Linux system this is: export OSG_GL_ERROR_CHECKING=ON In my case this pointed me to a Texture2DRectangle that I was improperly declaring a min filter on. Hope this helps. -----Original Message----- From: osg-users [mailto:[email protected]] On Behalf Of Trajce Nikolov NICK Sent: Thursday, October 23, 2014 6:57 AM To: OpenSceneGraph Users Subject: [osg-users] invalid enumerant error Hi community, This is question for those who has debug OpenGL apps.
